The dangers of soil erosion in the hills of Jiangnan

The hazards of water and soil erosion in the hills of Jiangnan:

(1) Soil and water erosion causes the soil in hilly areas to thin and even form red stone deserts, and the ecological environment is severely degraded and difficult to reverse;

(2) The red soil lost in hilly areas covers the paddy soil in the lower part of the hills, leading to the degradation of cultivated land;

(3) Severe water and soil erosion makes the terrain of hilly areas more complex and undulating. Heavy rains may trigger geological disasters such as mudslides;

(4) Soil erosion causes the sediment content of rivers to increase and the river beds to rise, exacerbating flood disasters and threatening river navigation;

( 5) The sediment content in rivers increases and the water quality of rivers deteriorates, affecting water use in nearby areas.

Measures for management:

(1) Close mountains for afforestation, plant Pinus tabulaeformis, Masson pine, tea trees, etc. to conserve soil and water;

(2) Adjust agricultural structure, Convert farmland to forest in hilly areas, strictly prohibit land reclamation on steep slopes, and develop agriculture according to local conditions;

(3) Take measures such as creating firewood forests, developing small hydropower, and developing biogas to solve rural life energy problems;

(4) Carry out small watershed management and take measures to encourage individuals and enterprises to contract barren hills;

(5) The state should provide relevant policy, financial and technical support;

(6) When necessary Carry out ecological migration.
